Paris Fashion Week just finished last week, but next season's gowns are already hitting the red carpet. If you were curious as to how the bevy of sheer, boudoir-inspired gowns would translate from the runway, look to Michelle Williams for a lovely, slightly more modest take. For the New York premiere of her upcoming Marilyn Monroe biopic My Week With Marilyn, Michelle chose the seafoam green chiffon gown from Dior's Spring '12 collection. She added a slip, the belt from the show, and a cocktail ring. Michelle kept her makeup minimal, going for dewy skin. We love the fresh, glowing, elegant look.
